To all whomit may concern:

'Beit lmown that .L Howann L. MAsoN, a citizen of" the United States, residing at Kansas City, in the county of Jackson and 5 State of Missouri, have inventedcertain new and useful.- Improvements in Electrically- Controlled Hood-Locks, of which the following is a specification.

-My invention-relates to electrically-com trolled locks, .and it is particularly adapted 1 to the-locking of an automobile hood, so that "access cannot be gained to the automobile ignition system for the purpose of starting thefautomobilejduring the absence of the owner. f In ordenthat the .invention may be fully understood, reference will now be made to the accompanying drawing, in which: Figure llis a side elevation partly insection-of the lock inposition on an automobile. 2 is an irregular vertical section on line II 'II of Fig. 1. Fig. 3 is a diagram of theelectriccircu tfor controlling the lock. j

A 'designatesa broken. portion of a hood of the type hinged at the top.

which the hood A rests when closed.

' l 1 designates the case for my lock, said case being secured to the inner side of the member. B of the chaseis. a1 ,2 desi ates a u rigi secured to the inner sidi; of the hod dA.

3 designates abolt adjustably extending throughan opening inlug 2 and secured at V any'point-of its adjustment by a set-screw' 4. opening 5 is provided in the top of case 1 to'permit the lower portion of the bolt .3 to enter said .case when the hood is closed.

. designates lat h m unt d in the upper portion of case-1 uponthe rectangular or- I ti on of'a shafl 7, journaled. in one side o the ..case and a bearing Ssecured to the'i'nterior .of saidcasealOne endof shaft -7 projects from the case landis provided with a knob 9, whereby the shaft-Tmay be rocked to' dis gag e la h 11 Q 'b0 {Bolt 3 has ashoulde'r 10fo r engagement with a corresponding shoulder 11 at the upper portion of the latch 6, which is. auto- 50 matically rocked into engagement Twithsaid t bolt by a coil spring 12. ring 12 loosel iii embraces a hub 13 of the latch 6 to whic one of its ends is secured, the opposite, end of said spring beiug secured to a partition I noid magnet 24;.

. of'a battery 25, controlled switch 27. Switch 27 may be concealed about the alltomobile'at a place known only to the owner, or said switch-may 'thefi bolt. p a v If the hood consists of two hinged sec-- 14 dividing the upper and lower portions of the case 1.

The lower end of bolt 3- has a beveled side 15 which contacts a correspondingly beveled side 16 at the upper end of the latch and rocks thelatter back against the action of the spring 12 to allow the bolt 3, to pass down to the position shown on Fig. Latter stop-pin 19 on the interior of the case 1.

When the latch 6 is in engagement with the bolt 3 as disclosed by Fig. 1, it is locked in such engagement by the armature 20 of a solenoid 21 entering a notch 22 in the lower end of said latch 6. Armature 20 passes through an opening 14"v which acts as a guide The armature 20- is in the partition 14, for said armature. automatically forced into the notch 22 by a nonmagnetic spring hollow core of the sole 23, arranged in the The solenoid 21 is in a circuit consisting wires 26, and a manuallybe controlled by a combination lock, so that it cannot be closed without first. solving the combination.

Normally the hood A cannot be raised owcan readily unlock the same on' closing switch27, which inturn closes the battery circuit, energizing the solenoid which attracts its armature 20 out of engagement with the notch 22, thus leaving, said latch free to-be rocked-out of engagement with '1 I tions, "a lock i'sprovidedforeach section.

a bolt secured to said element, a casing secured to the member and provided with an opening to receive the' bolt, a rock-shaft Having thus describedmy inventiom what'.

mounted in said casing and projecting from one side thereof, a knob on the projecting end of said rock-shaft, a latch fixedlymounted'upon said rock-shaft and adapted to engage the bolt, a spring to force the latch into engagement with the bolt, a solenoid having an armature to engage thelatch and hold the same in engagement with the bolt,

and resilient means to force said armature into engagement with the latch.

2. In combination with amember to be locked and an element to be locked thereto, a lug secured to the inner side of the element, a vertically arranged bolt mounted inv to the member and ening in its upper wall for the e lower end of the bolt, a rock said lug, a casing secure having an o passage of t shaft mounted in the casing and projecting from one side thereof, a knob on the pro ecting end of said rock shaft, a latch fixedly mounted upon the inner end of said rock shaft and adapted to engage the bolt, said the latch, substantially as shown and de-' scribed.

In testimony whereof I aflix my signature, in the presence of two witnesses.
